Factory robots are now mastering the fine art of filleting fish. Harry Westavik’steam at SINTEF Fisheries and Agriculture in Trondheim, Norway, is developing a system that can fillet farmed fish with the help of a laser that captures 3D colour images of the animal.

Algorithms analyse the images to work out the best place to cut, before a robot armtakes over. The system can be trained to distinguish between different species, allowing it to sort fish by type. It can also determine weight by estimating volume from images, then applying the typical density of a fish. Read more …
